1. A door system, comprising:
a doorframe having opposing vertical jambs;
a door pivotably coupled to the doorframe;
a threshold extending between the opposing vertical jambs and providing a first upper surface, a second upper surface, first and second valley surfaces extending from the first and second upper surfaces, respectively, such that the first and second valley surfaces slope toward each other, and a trough base extending between the first and second valley surfaces, the first and second valley surfaces defining a valley;
a dam removably mountable to the threshold and providing a projection extending downward from a bottom of the dam and sized to be received within the valley, the projection comprising:
a first dam surface complementary to the first valley surface, wherein a first gap is defined between the first dam surface and the first valley surface;
a second dam surface complementary to the second valley surface; and
a dam base extending between the first and second dam surfaces and contacting the trough base; and
a valley seal positioned in the first gap when the dam is mounted to the threshold and thereby generating a sealed interface between the dam and the threshold, wherein the threshold further provides third and fourth valley surfaces extending transversely from the first and second valley surfaces, respectively, and first and second trough surfaces extending transversely from the third and fourth valley surfaces, respectively, and transversely from the trough base, the projection further comprises: third and fourth dam surfaces extending transversely from the first and second dam surfaces, respectively, and transversely from the dam base, wherein the third and fourth dam surfaces contact the first and second trough surfaces, respectively.
